[yocto] Kernel driver installs broken in poky2.3

[Valluri, Amarnath]

Hi Jeff,

Sorry to hear about the failure,

The change was part of adding merged /usr support for oecore. 'INSTALL_MOD_PATH' was using '/lib/modules/${KERNEL_VERSION}' as kernel modules path, where as in merged /usr environments it would  be '/usr/lib/modules/${KERNEL_VERSION}'., And there is no way to fix this by using INSTALL_MOD_PATH, So I had to use MODLIB by replacing hardcoded '/lib' with appropriate bitbake variable .ie., ${nonarch_base_libdir}.

Poky release, pyro (2.3), file: meta/classes/module.bbclass

This change, made in January 2017, is breaking  do_install's for our kernel drivers, as INSTALL_MOD_PATH is not defined.  Our Makefiles reference this variable.

What was the purpose of this particular change?

    kernel: use ${nonarch_base_libdir} for kernel modules installation.



    Replace hardcoded '/lib' in kernel modules installation path with

    ${nonarch_base_libdir}, which is meant exactly for this.
